What makes soap interesting? Why choose one brand over another? Dichter’s first contract was with the Compton Advertising Agency, to help them sell Ivory soap. Market research typically involved asking shoppers questions like “Why do you use this brand of soap?” Or, more provocatively, “Why don’t you use this brand of soap?” Regarding such lines of inquiry as useless, Dichter instead conducted a hundred so-called “depth interviews”, or open-ended conversations, about his subjects’ most recent scrubbing experiences.
The approach was not unlike therapy, with Dichter mining the responses for encoded, unconscious motives and desires. In the case of soap, he found that bathing was a ritual that afforded rare moments of personal indulgence, particularly before a romantic date (“You never can tell,” explained one woman). He discerned an erotic element to bathing, observing that “one of the few occasions when the puritanical American [is] allowed to caress himself or herself [is] while applying soap.” As for why customers picked a particular brand, Dichter concluded that it wasn’t exactly the smell or price or look or feel of the soap, but all that and something else besides—that is, the gestalt or “personality” of the soap.
